Thanks for your time on this criggie, I also prefer option 4, as I have 
the frontends and wired LAN connections to them now.  Its easily syncing 
the material on multiple places that's the problem I'm looking to solve. 
  Option 3 would also achieve that, however running many lengths of CAT5 
is the major roadblock to that idea.

Option 1 is curious, as you said seems to require software drivers on 
the master, does not say supports linux. Why is it limited to 4 clients? 
  Seems that it works on an existing LAN, which asks the question how 
exactly?  Couldn't find a manual to explain further.  Probably does 
something similar to what I asked in the OP, with "drives" running like 
VLC, pulling the desktop and sending it out in some IP fashion, at a 
guess I'd say it sends 4 unicasts.
